An experimenter who tests a hypothesis and observes an anomaly that conflicts with his knowledge and views, normally reacts by suspecting some sort of mistake. When he has excluded this possibility, his second sensible reaction is to find an ad hoc interpretation to explain the anomaly. When his favorite interpretation is interesting, probable, simple, elegant and testable enough, he can experiment to verify this explanation as a new hypothesis, independently from the anomaly. This article describes how a scientific investigation walks on two legs: one leg of hypothesis testing and a second leg of anomaly explaining.
一位检验假设并观察到与他的知识和观点相冲突的异常现象的实验者，通常会通过怀疑某种错误来做出反应。当他排除了这种可能性后，他的第二种合理反应是找到一种特设解释来解释该异常现象。当他最喜欢的解释有趣、可能、简单、优雅且足够可检验时，他可以进行实验以验证这个解释作为一个新的假设，独立于该异常现象之外。本文描述了科学研究是如何两条腿走路的：一条腿是假设检验，另一条腿是异常现象解释。
